yeah munin does use alot of resources, i actually turned mine off, but that is a personal choice.

that message is coming from the CFS, your using config server firewall right.. well down near the bottom of the config prob about 3/4 the way down is the settting for that. Just look for 200 and increase it..

Hi Duran, thanks for taking the time to respond. I'll be increasing the limit, but do you feel Munin is the type of plugin that could be running from time to time. For instance, I could turn Munin off and do weekly scans with it or something like that? I'm just trying to get a feel for the best way to run the service, as I do like the added monitoring that it gives.

I dont see a problem with running it once in a while, but there might be some stats that are accumulated that you may not get if you do that. I honestly dont know enough about it tech wize to know for sure. All you can do is give it a shot and see if it gives you the information that you need doing it that way.

I suggest leaving it enabled as it is unless you are experiencing issues with lack of memory on your system. It's okay for applications to utilize the available memory on a system, and unless you are experiencing slowness or a lack of available memory for other applications, it's typically not going to be an issue.

You may want to experiment with disabling some of the Munin plugins you don't care about to reduce it's processing time.

For example disabling the mysql_innodb plugin makes a noticeable difference. I also have the yum plugin disabled.

You can move the links found in /etc/munin/plugins outside of that folder. I basically created a /etc/munin/plugins_removed folder to put them in.

Then just run the following to restart Munin.

service munin-node restart

You can also run the following to list the which plugins/features are on or off.

munin-node-configure

Note that if Munin is updated by cPanel, it will re-activate the plugins, but they don't update very often, but it would be great if they did since there's a large update to munin that's been out for a while.

I have also disabled munin as it was a huge resource killer on my boxes...

is there any way we control for what it runs and make it work without using mysql ???

I had literally hundreds of queries in information schema for like every second !!!!!!

Mine doesn't use any mysql at all as far as I can see. I have a munin_innodb database but it's empty.. maybe because I have that munin plugin disabled. My Munin updates average only 5 seconds to process, but that will vary depending on your server specs.

My munin is not doing dozens of mysql connections per second. I don't even seen anything significant when munin updates every 5 minutes. Again this may be due to disabling the mysql_innodb plugin for munin. I know it makes a dramatic difference in the 5 minute update time and perhaps is the resullt of your transaction traffic.
